In recent months, Jenner, who used to document her every move for fans on Snapchat, has chosen to remain completely under the radar — rarely emerging in public and using her social media platforms mostly to promote her brand.

“Kylie wants to disappear and be out of the spotlight and focus on her health and happiness,” a source close to the family told PEOPLE on Tuesday.

“She isn’t going to publicly address her pregnancy until she gives birth,” the source said. “She’s not doing any public appearances and just wanted to take six months off.”

A separate source told PEOPLE last week that Jenner “is only trusting her closest friends and her sisters right now.”

“She wants to reveal things on her own terms but she’s of course having fun teasing everyone,” the source said. “She knows all the attention is on her and her baby bump, but she won’t share until she wants to.”
